This map shows Hodapp's Addition to the community of North Mankato. Wendell Hodapp was the community's first president, who had purchased 160 acres of land in 1878 that included a significant portion of the future city.
This map shows the village of Traverse des Sioux along the Minnesota River. The village was named after the Traverse des Sioux, which was the French name for the crossing site of the river by the Dakota people who lived in the vicintiy.
